Troubleshooting at the remote control LCDREMOTE CONTROL (option)

This is possible only on the wired remote control.

Self-diagnosisIf an error occurs, the following display will be shown.

If "CO" appears in the unit number display,there is a remote control error.Refer to the installation instruction sheetincluded with the remote control.

SPECIAL INSTALLATION SETTING

PUMP DOWN (Refrigerant collecting operation)

1. When the product is stopped:

Perform the following procedures to collect the refrigerantwhen moving the indoor unit or outdoor unit

1

2

3

4

Press the PUMP DOWN switch on the outdoor unit.(The LED on the outdoor unit circuit board starts flashing.)(1 sec. on / 1 sec. off repeated)

The pump down operation (cooling operation) beginsright away. After oparation starts, close the three-wayvalve (liquid).

After 2 - 3 minutes, operation stops. Close the three-wayvalve (gas) within one minute after operations stops.

The LED will go out three minutes after it stops.Disconnect the power supply after confirming that theLED has gone out.

2. When the product is operating:

1

2

3

4

Press the PUMP DOWN switch on the outdoor unit.The LED on the outdoor unit circuit board starts flashing( 1 sec. on / 1 sec. off repeated), and operation stops.At this point, recovery has not been completed, so do notclose the three-way valves. (liquid and gas)

The pump down operation (cooling operation) be-gins after three minutes. Close the three-way valve(liquid) after operation starts.

After 2 - 3 minutes, operation stops. Close the three-wayvalve (gas) within one minute after operations stops.

The LED will go out three minutes after it stops. Dis-connect the power supply after confirming that the LEDhas gone out.

*When the pump down operation is repeated, temporarilydisconnect the power supply after opening the closed valves(both liquid and gas).Reconnect the power supply after 2 - 3 minutes and performthe pump down operation.

*When the start of the operation after pump down operationhas been completed, temporarily disconnect the power supplyafter opening the closed valves (both liquid and gas).Reconnect the power supply after 2-3 minutes and be sure toperform a test operation for cooling.
